GEORGE W. GILL, foE BATTLE CREEK, MICHIGAN., 4Assienon or QuE-FOURTH me i "WILLIAM L. CARROLL, oNE-Eouiwn rro BEENiEW. .warrig AND N-FOURTH To 'CARL sANBEEG, or 'BATTLE CREEK, MICHIGAN. 'Y 'f Be it known that I, citizen ofthe United States, residing at Battle Creek, county of Calhoun, State of Michigan, have invented certain new and useful Improvements in Engines or `Motors,

of which the following is a specification.

This invention relates to improvements in engines or motors. Y

My vimproved engine or motor isespecially designed-by mefor ringing the bellof a locofmotive valthough it is readily adapted and desirable for use in other relations.

I have illustrated my improvements'asI have embodied them as a bellringing motor.

The main objects of thisinvention are: First, to provide an improved motor or engine kfor ringing the bell of 'a locomotive,

which imparts a full stroke to the bell but does not permit it to revolve or hang up.

Second, to provide an improved motor or engine having these" advantages which is comparatively simple and economical in structure and very durable in use, and oney which isnot likelyto get out of repair or become inoperative.

Further objects, and objects relating to structural details, will definitely` appear from the detailed description to follow.

`I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed Vout in the claims..

A. structure which is a preferred embodimentfof my invention is clearly illustrated in the accompanaying drawing-forming a part of this specification, in which:

Figure I is a side elevation of a'structure embodying the features of my invention, same being shown mounted 4upon a locomotive which is shown in section on a line corresponding to line 1-1 of Fig. II.

Fig. II is a detailside elevation looking from the right of Fig.-I, the movement/of certain parts being indicated by vdotted lines.V

VFig. III is an enlarged detail view partially in verticalV section on a line correspending to line 8-3 of Figs. V and VI, the exhaust valve carriedby the piston being shown in its seated position, the piston being at the innery end of its stroke.

. the exhaust valve carried bythe piston being open, the'piston being at the outer end adapted'vto be operated by means of va ropeor the like.V At its other endithe crank 4 has an 'arm 6v provided with awrist pin 7. These parts have been shown conventionally as their structure is well-known.

My improved Aengine or motor comprises cylinder 8 having heads 9 and 10 which, in the ystructure 4illustratecLIare' threaded thereon. .A gasket .disk 11 is providedfor the outer head 9. The inner head 10 is secured upon the bracket y12y by means of screws 12, thereby supporting the cylinder in an upright position.y The'cylinder is provided with side ports 13 and 14 spaced from its ends, the lower end of the cylinder constituting -a work chamber and the upper end a dash pot chamber. I have used the terms upper and lower mainly for convenience in description. e Between the 'ports 13 and 14, the cylinder has longitudinal slots 15.' T hepiston lcarries a piston pin 17 engaging the pitman yoke 18 which -is yarranged to embrace the upper end of the n piston. The pitman 19 has a slide 20 mounted thereon for limited sliding movement, the wrist pin- 7 being engaged with 'this slide, the purpose ofthis slide connection being to allow the bell to swing under the impulses of the engine.

In the inner end of thepiston is a tubular valveeasing 21 havingaseat 22 therein for the plunger valve 23.' The valve casing has a relief port 24 ink its outer end communicating with the annular grooveV 2,5 ofl the piston pin 17 whichi'ha's a series of longitudinal grooves 26 therein communicating withzthis annularl groove 25 therebyproi valve casing 21 at the innerside of the valve seat.. An inletvalve casing designated gen-k erally bythe numeral 28 is threaded into the head 10"of the cylinder centrally below the valve 23, the inlet valve casing being connected by the pipe 29 to a source of supply such as compressed air or steam. The inlet valve 30 is adapted to seat upwardly against the seat 31, and projects .into the work chamber ofthe cylinder in alinement with the valve 23, so that on the return stroke of the piston the inlet valve is unseated or opened. The screw 32 supports the-valve in its open position andV provides an adjusting means for timing the valve.

VTo guide and support the pitman yoke, I mount a sleeve 33 upon the cylinder and slides 34 in the longitudinal slots of the cylinder to be engagedby the pin 17. With the parts thus arranged, the operation of the device is as follows:

lVith the parts in their initial position as shown in Fig. III, except that the valve 23 is there shown closed, on the admission of motive fluid, valve 23 is first vautomatically closed by the action of the fluid, the piston then being subject to the action of the fluid is actuated andthe inlet valve 30 is automatically seated or closed, which, however, does nottake place until a full charge of the motive fluid is admitted to the cylinder. When the piston uncovers theexhaust ports 13, the cylinder exhausts therethrough, and owing to the chamber then vbeing open to the atmosphere, the sustaining pressure on the relief valve is removed and the valve becomes unseated or` opens and drops upon th-e valve 30. v

The energy of the motive fluid and the impetus of the/bell carries the piston upwardly closing the port 14 and the u per end of the piston acts as a dash pot Vto c eck .the piston. The lost motion connection be-v tween the pitman and the bell described permits a full stroke of the bell but prevents its turning over completely. The weight of the bell and the reaction on the piston of the dash pot returns the-piston to its normal or initial position and unseats the inlet valve which again admits the motive fluid and the operation is repeated.

My improved bell ringing device is simple and economical in its parts, and is very durable and not likely tog-et out of repair.

, I have illustrated and described invention in the form in whichrI have embodied the same in practice. I have not attempted to illustrate or describe other modifications and adaptations as I believe the disclosure made will enable .those skilled in 'the art to which my invention relates to embody or adapt the same as may be desired.

Having thus described my invention,"what I claim as new Vand desire to secure by Letters Patent is: J
